230VAC Dimmable LED Driver
General Description
This demonstration board utilizes the
AL1697 Buck-boost LED driver-converter
with single winding inductor providing a
cost effective triac dimmable solution for
offline high brightness LED applications.
This user-friendly evaluation board provides
users with quick connection to their
different types of LEDs string. The
demonstration board can be modified easily
to adjust the LED output current and the
number of series connected LEDs that are
driven.
A BOM, schematic and layout are included
that describes the parts used on this
demonstration board, along with measured
performance
characteristics.
These
materials can be used as a reference design.

6.
Preset the isolated AC source to 230VAC.
Ensure that the AC source is switched OFF or disconnected.
Connect the anode wire of the LED string to the LED+ terminal of the evaluation board.
Connect the cathode wire of the LED string to the LED- terminal of the evaluation board.
Connect two AC line wires to the AC-L and AC-N terminals on the evaluation board.
Ensure that the area around the board is clear and safe, and preferably that the board and
LEDs are enclosed in a transparent safety cover.
7. Turn on the main switch. LED string should light up with LED.
DO NOT TOUCH THE BOARD, LEDs OR BARE WIRING.
Caution: The AL1697 is a non-isolated design. All terminals carry high voltage
during operation!
